U1 Ch.1 Intro to Chemistry Quizs

What is scientific inquiry?

• The process of asking questions and seeking answers through experiments and observations.

• A method of memorizing facts and figures.

• A way to conduct surveys without any experiments.

• The practice of reading scientific literature without questioning.

What are the main branches of chemistry?

• Organic, Inorganic, Physical, Analytical, and Biochemistry

• Physical, Chemical, Environmental, and Theoretical

• Organic, Inorganic, Environmental, and Industrial

• Analytical, Biochemistry, Theoretical, and Quantum

What is a scientific theory?

• A scientific theory is a guess about the natural world.

• A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of evidence.

• A scientific theory is an untested hypothesis.

• A scientific theory is a personal belief about nature.

What is matter in chemistry?

• Anything that has mass and takes up space.

• A substance that can be seen but not touched.

• A form of energy that can be measured.

• A chemical reaction that produces heat.

What is the scientific method?

• A systematic approach to research involving observation, hypothesis, experimentation, and conclusion.

• A method used only in scientific experiments without any observation.

• A way to conduct research that ignores hypotheses and conclusions.

• A process that answers multiple questions at once.

What is the difference between pure science and applied science?

• Pure science focuses on practical applications, while applied science is theoretical.

• Pure science seeks to expand knowledge, while applied science uses that knowledge to solve practical problems.

• Pure science is concerned with technology, while applied science is about basic research.

• Pure science and applied science are essentially the same, with no significant differences.

What are the types of scientific investigations?

• Experiments, observational studies, and simulations.

• Surveys, interviews, and case studies.

• Theories, hypotheses, and conclusions.

• Data collection, analysis, and reporting.

What is the difference between organic and inorganic chemistry?

• Organic chemistry studies compounds without carbon, while inorganic chemistry focuses on carbon-containing compounds.

• Organic chemistry focuses on carbon-containing compounds, while inorganic chemistry studies compounds without carbon.

• Organic chemistry is concerned with metals, while inorganic chemistry deals with non-metals.

• Organic chemistry is a branch of biology, while inorganic chemistry is a branch of physics.

What is the difference between a scientific theory and a scientific law?

• A scientific theory describes how phenomena occur, while a scientific law explains why they occur.

• A scientific theory is a proven fact, while a scientific law is a hypothesis.

• A scientific theory explains why phenomena occur, while a scientific law describes how they occur.

• A scientific theory and a scientific law are the same thing.

What is a scientific law?

• A theory that explains a phenomenon based on limited observations.

• A statement based on repeated experimental observations that describe some aspect of the world.

• An unproven assumption that requires further testing.

• A hypothesis that has been tested only once.
